Question

using the
as\ idea, how many electrons are
eeded\ for the compound sicl4? 24 40 32

Explanation:

Step1: Determine the valence electrons of each atom

• Silicon (\(Si\)) has \(4\) valence electrons.
• Chlorine (\(Cl\)) has \(7\) valence electrons.

Step2: Calculate the total number of electrons needed using the NAS (Number of Atoms × Stable electron configuration) idea

• For \(SiCl_{4}\), there is \(1\) \(Si\) atom and \(4\) \(Cl\) atoms.
• The stable electron configuration for \(Si\) (like noble gas) is \(8\) electrons and for each \(Cl\) is also \(8\) electrons.
• Total electrons needed \(=1\times8 + 4\times8\)
• \(=8+32\)
• \(=40\)

Answer:

\(40\)
